Marieke H Rosenbaum - DVM, MPH, MS

Marieke H Rosenbaum
Research Assistant Professor
Public Health, Global Health, Community Health, Epidemiology, Zoonotic Disease

            Marieke Rosenbaum is the Track Leader for the Combined DVM-MPH pathway at the Cummings School of Veterinary Medicine with a secondary appointment in the Department of Public Health and Community Medicine at the Tufts University School of Medicine. Prior to her current career, Dr. Rosenbaum was a licensed wildlife rehabilitator at WildCare, Inc., in Orleans, MA, as well as an aquarist in the Penguin Department at the New England Aquarium. While pursuing her veterinary and public health training at Tufts University, she completed a 2-year Fogarty International Clinical Research Scholars program in Peru where she studied infectious diseases among primates involved in the wildlife trade, and leptospirosis in livestock, dogs, and wild rodents in an area of the high jungle were this disease is endemic in rice cultivators.  

            Her academic and research interests are focused on health and disease in the context of human-animal relationships. Her current global research activities include studying infectious disease ecology in Peruvian nonhuman primates from a variety of interfaces for human-primate interactions (ie wetmarkets, pet primates, sanctuaries, road side attractions), and how cohabitation with production animals may affect the microbiota of Guatemalan children. Locally, Dr. Rosenbaum studies lead and Salmonella in urban chicken flocks, and Staphylococcus aureus carriage and antimicrobial resistance in greater Boston’s urban rodent population. In addition, Dr. Rosenbaum has embarked on research aimed at improving the quality of life for veterinarians and veterinary trainees who also wish to raise a family.

General Research Interests

  • Urban agriculture and animal production
  • Tuberculosis in nonhuman primates
  • The Peruvian wildlife trade
  • Infectious diseases in urban rodents
  • Parenting and family planning amongst veterinarians

Selected Research Projects

  • The CLUC Study – Chickens Living in Urban Coops. Backyard poultry flocks are increasingly popular in urban areas. In this study we use a One Health approach, integrating veterinary medicine and environmental health epidemiology, to understand public health risks associated with urban poultry ownership in the greater Boston area. The capacity to understand this dynamic human-poultry-environment relationship amid a burgeoning industry will strengthen our ability to make husbandry and safe handling recommendations that can be evaluated and instituted through the engagement of local community stakeholders and leaders.
  •  Cohabitation with Production Animals and Gut Microbiota in Guatemalan Children.  Perturbations in the gut microbial community (microbiota) may impair intestinal permeability, leading to local and systemic inflammation. Exposure to human feces is associated with adverse health outcomes and improved sanitation has long been recognized as an important public health measure in developing countries. However, it is not known if exposure to animal feces through co-habitation with production animals (poultry, pig, goats, sheep and cows) impacts the gut microbiota and the health of children.
  • Urban Wild Rodents as Environmental Reservoirs for infectious diseases. Wild rodents in urban centers are frequently identified as the hosts and reservoirs for zoonotic pathogens such as Rickettsia, Leptospira and Hantavirus in the urban environment. Recent evidence indicates that rodents may also acquire human pathogens due to contact with human food and biological waste. This study systematically evaluates rodents as reservoirs of infectious diseases and employs the use of advanced genome sequencing techniques to identify genomic linkages among strains carried by rodents and humans.
  • Pregnancy, parenthood, and family planning among veterinary trainees. Veterinary students and house-officers work rigorous schedules with unique demands on time, resources, and personal well-being. The veterinary profession is now female dominated at most levels and veterinary training overlaps with peak reproductive age for the majority of students and house-officers. There exists no demographic data on the number of veterinary students or house-officers who experience pregnancy, are parents, become parents during their veterinary training or alter family planning due to their training.Furthermore, it is unknown if policies for parental leave, facilities for pumping and/or accommodations for pregnant trainees or parents of young children are in place at veterinary teaching institutions. As the veterinary profession continues to evolve, understanding the unique needs to veterinary trainees with regards to parenting and family planning will inform veterinary institutions at large about how to develop best practices and improve quality of life for this demographic.
  • Infectious diseases in wild caught Peruvian Neotropical primates.Primates are phylogenically similar to humans and bi-direction transmission of infectious diseases can occur between humans and primates. Peru is home to over 30 species of Neotropical primates and contact between human and primates is increasing due to the lucrative wildlife trafficking industry, habitat encroachment, and via the expansion and overcrowding of zoos, sanctuaries, and even restaurants that keep captive primates as tourist attractions. There are documented and anecdotal reports of zoonotic diseases such as tuberculosis and herpesvirus in primates in Peru. In addition, it is unknown how the newly emergent Zika virus in South America may circulate in primates, or if primates may act as a reservoir for the virus.  Herpesvirus, Zika virus, and tuberculosis are significant health problems in humans in Peru, yet relatively little is known about how these pathogens behave in semi-domesticated nonhuman primates, who frequently interact with humans in a diverse range of contexts while also having contact with wild, free-roaming nonhuman primate groups.
